Process for producing a styrene polymer and a catalyst for use therein.

摘要

There are disclosed a process for producing a styrene polymer having a high degree of syndiotactic configuration at a reduced cost and an enhanced efficiency, and a catalyst to be used therefor which comprises (A) a specific transition-metal compound, (B) a specific coordination complex compound and (C) a compound having an alkyl group. The catalyst according to the present invention is inexpensive compared with the conventional catalyst containing aluminoxane as the major ingredient, and exhibits a high activity in polymerizing a styrenic monomer into styrene polymer with a high degree of syndiotacticity as well as a high yield and conversion rate.
